Problems solved by technology

In this case, the locking bolt cannot be pulled out from the steering shaft by the driving force of the motor, and the motor becomes overloaded and an excessive current flows into the motor, so the motor generates heat.
In addition, if the unlocking operation is repeated until the lock bolt is pulled out from the steering shaft, the motor will become hot, and thermal failures such as coil disconnection of the motor may occur.
[0009] In order to solve the above problems, it has been considered to equip the motor with an overheat protection device composed of bimetal, etc., but this will make the motor bulky and cost increased.

Abstract

The electrically actuated steering wheel lock device (1) has a carriage bolt (7) which is displaceable between a locking position, in which the carriage bolt is engaged in a steering shaft of a vehicle, and an unlocking position, in which the engagement is released. The unlocking operation is performed in the normal mode by a control unit which controls an electric motor (13) based on the exposure time, in which the predetermined power supply is maintained for the electric motor, and the unloaded time, in which the power supply is interrupted.

Description

technical field [0001] The invention relates to an electric steering locking device for locking the rotation of a steering wheel in an electric manner when a vehicle is parked. Background technique [0002] In recent years, in order to prevent theft, some vehicles are equipped with an electric steering lock device, which is used to lock the steering wheel electrically when parking. Such an electric steering lock device includes: a lock bolt capable of moving between a locked position engaged with the steering shaft of the vehicle and an unlocked position released from such engagement; A control device for performing locking / unlocking processing, and a position detection device electrically connected to the control device to detect at least that the locking bolt is in the unlocked position. [0003] With the above-mentioned electric steering lock device, once the driver turns off the engine on / off switch while the engine is working, the upper ECU on the vehicle body that det...
